The purpose of'myinvention is to render possible to the respiratoryorgans the direct int-akingbf a pulverulent medicamen'ted mixture thatfurnishes to the'human organismthe means to remedy a deficiency ofcalcifying and mineralizing salts, so as to facilltate the calcificationof pulmonary lesions and the normalization of the calcic metabolism inexhausting diseases; and so that the pulverulent mixture reaches themain respiratory organs and does not stopun the primary respiratorypassages, 1t 1s lnhaled in a current of compressed air that is warm anddry. My apparatus supplies a medicamented mixture, under pressure, tothe patient as he inhales, so as to reach to the parts of the lungs thathave tended to stopfunctioning. Preferably, the pressure is due tocompressed air, and the air is supplied dry by being heated.

I attain these objects by means of the apparatus illustrated in theaccompanying drawings, in which:

Fig. I is a view of the apparatus as designed for institutions,hospitals, and other places where a plurality of patients can besimultaneously treated.

Fig. II is a View of a smaller type of apparatus designed for privateuse.

Referring to Fig. I, the apparatus consists of a pedestal with anelectric motor and apparatus for the compression of air, with electricresistances for the warming of same, and an air chamber, quadrilateralor polyhedral in shape, in which is placed the reservoir for thepowders, leading to the charging tube and to the distributing tubes.

The operation of the apparatus is described with reference to Fig. I andto the parts indicated thereon by letters, as fol lows:

A is a metallic tube through which the pulverulent material which is tobe inhaled is forced into the surrounding atmosphere, if this method ispreferred to that of direct inhalation by means of the mouthpieces. Thesaid tube A passes through B, the distribution chamber, and is also usedfor the purpose of charging, i. e., permitting the filling of, C, thereservoir for the powders, which connects with B.

B is the distribution chamber and is equipped with outlets for thepassage of the powders to the mouthpieces, from which the patientinhales the powders perfectly 2111+. hydric with Warm,.'dry, compressedair.

C is the reservoir for'thepowders, with very small holes to permit thepassage of the compressed air, so that the powders are forced into B,the distribution chamber and from there to the mouthpieces.

D is the air chamber, which accumulates the necessary quantity of warmedair to feed the mouthpieces.

E are peep holes, hermetically closed by means of clamp screws, topermit thermodried by electric coils or other suitable ap-V paratus. Thewarm dry compressed air accumulates in the chamber D, subject to controlby the air and heat regulators at F, and passes from D through the smallapertures in the reservoir 0, which reservoir is filled with a suitablemedicated powder or other substance. The air pressure drives the powderinto the distribution chamber B, and from B the mixture of air andpowder is driven out through the tubes to the mouthpieces, from whichthe patient inhales the mixture. Suitable cocks control the passage ofthe mixture from the distribution chamber B to the mouthpieces.

If desired, the mixture can be driven directly from G through the tube Ainto the surrounding atmosphere, vif this method of use is preferredtothat of direct inhalation through the mouthpieces.

The smaller apparatus shown in Figure II, is substantially similar inoperation to the larger machine. It consists essentially of a motor andcompressor which forces the air through a tube, where it becomes warmed,

into a reservoir, from which the powders are expelled through amouthpiece.

This apparatus may be described by reference to its parts, which arelettered as follows:

A is atube for the outlet of the mixture,

and is provided with a mouthpiece for conveying the mixture to thepatient.

B is a reservoir for the medicated powders, which is perforated to allowthe passage of compressed air.

0 is an air chamber which accumulates the necessary quantity of warm airto force the powder through the tube A.

D is an air compressor with apparatus for warming the air.

E is a clamp screw to regulate widening or narrowing the aperture inchamber C and controlling the outlet of the mixture from tube A. v

Having v thus described my invention, I

claim (a 1,643,983 v a tively large quantity of compressed and heated.air, a medicinal powder container, having a plurality of minute orificestherein, and positioned to so hold. powder asxto be carried away withcompressed air from said chamber, a distribution chamber positioned toreceive carried away powder and air, and controllable-dischargemeansfrom said distribution chamber.
